Note: This root cause analysis (RCA) is from real-time scenarios that happened in industries during the tenure of one or two decades ago. These articles will help you to improve your troubleshooting skills and knowledge.
A turbo-compressor (K-601 T) Tilting Pads’ too high 108 to 110o C close to the 115o C trip pad metal temperature threatened surprise K‑601 T trip and hence total indefinite plant outage.
A skilled Japanese technician from the manufacturer working in a neighboring plant suggested scrapping the Babbitt as in fig. However, he declined doing it due to heavy current task deadlines.
Undaunted, the author inspired and guided as under plant crew scraped the pads successfully the very first time.
These pads installed in the machine taking a 2‑hour plant shutdown (SD) attained max metal temp 98oC even in hottest ambient temperature summer months, eliminated the K‑601 T trip threat forever, and put all in peace!
